SOLAR HEATER.

SPECIFICATION forming part of Letters Patent No. 705,350, dated July 22, 1902.

Application filed September 24, 1901. Serial No. 76,422. (No model.)

To all whom it may concern;

Be it known that I, PHILIP G. HUBERT, a citizen of theUnited States, and a resident of State of New York, have invented a new and useful Solar Heater, of which the following is afspecification.

My invention relates to a solar heater for use'in connection with a tank of-liquidwater, for exam'ple"the object being to provide a heater for general household use to keep, a

I body ofheated water on hand. A practical embodiment of my invention is represented in the accompanying drawings,

in which Figure 1 is a view ofthe heater and tank in vertical longitudinal section, and Fig. 2 is a 7 plan view.

plate a through the thin film of water to the plate b,'keeping the two platesheated, and thereby heating the film of water from both the upper and lower sides. The plates at and b are united at their edges by a rim d, making the space between the plates an inclosed The tank for maintaining the supply of hot water is denoted by e. A pipe f leads from the tank 6, from a point at or near its bottom, to the lower corner of the heater formed by the plates 0, b and rim d, which heater is intended to be set in an inclined position facing the sun to take its rays directly on its face. The upper opposite corner of the heater is connected with the tank by a pipe g, leading to a point at or near the bottom of the tank, and is connected within the tank with a pipe 7t, hinged to the pipe 9 at 'i, its free end being suspended within the tank by a fioatj, so that the warm water at the surface within the tank may be drawn upon.

The outlet-pipe is denoted by 70. It is con nected with the pipe g at a point near the bottom of the tank'and will therefore supply warm water either directly from the heater or from the upper stratum of water within the tank.

It is intended that the space within the heater shall be a little greater than the capacity of the pipes leading from and to the tank, so that the stream of water flowing from the tank and spread out in a broad thin film to be heated on its return to the tank will not be to any great extent impeded in its movement from and to the tank. The circulation is kept up by gravity induced by the heated water in the heater, audit is intended that the pipes and tank shall be so retain the heat.

In practice I have succeeded in heating the water in the tank to 144 Fahrenheit, and it has fallen by 10 Fahrenheit during the night.

The heateris simple, effective, and may be furnished at-a comparatively slight cost.

It is obvious that slight changes might be resorted to in the form and arrangement of the several parts without departing from the spirit and scope of my invention. Hence I do not wish to limit myself strictly to the structure herein shown and described; but

What I claim is- Asolar heater comprisinga broad thin heating-chamber having its top and bottomplates so spaced as to spread the water therein into a thin film, thereby causing the entire amount of water to come into close proximity to the one or theother of the plates, a tank, a pipe leading from the lower portion of the tank to the heating-chamber, a pipe leading from the heating-chamber to the upper portion of. the

packed as to liquid in'the tank, and a draw-off pipe connected-with the'pipe leading from the heating-chamber to the-tank,-the said pipe lead ing from the heating-chamber to the tank be ing provided with a swing-section supported by a float within the tank.

In testimony that I claim the foregoing as my invention I haye'signed my name, in pres ence of two witnesses, this 21st day of September, 1901.
